Box 511, Kingsport, Tenn. 37662 FiledSept. 5, 1967. Published Mar. 18, 1969 Class 117-17 1 Sheet Drawing. 16Pages Specification An electrostatic process and apparatus for applyingmaterials to tobacco smoke filter tow wherein the material is introducedinto an electrostatic field and is attached to the tow passing throughthe field. In order to attach a material such as liquids and/or solidparticulate matter to the filter tow, the material is passed over theedge of a charged surface which is at a high electrical potential withrespect to the closely adjacent tow carrying surface. The material isthus subsequently attracted toward, and deposited on the filter tow.Solid particulate matter can also be attached to the filter tow byintroducing the matter into the electrostatic field created between ahigh potential grid and a grounded surface. The particulate matter isformed into a cloud and deposited upwardly onto the filter tow that ispassing between the grid and grounded surface.
